Patent CA-2222674-A1 (CA)
Title: Control method and apparatus for power distribution network
Inventor: VELEZ ANDREW M
IPC: H02H7/26
Filed: 1997-11-26
Abstract: A control method and apparatus is provided for isolating network faults via the communication between neighboring network locations and the control of sectionalizing switches at the network locations. Control apparatus is provided at particular network locations which responds to detected fault conditions and communicates the detected fault condition to the control apparatus at neighboring network locations. The appropriate control apparatus, in response to the information received from neighboring network locations, opens a sectionalizing switch to isolate the fault condition. In one particular arrangement, each control apparatus that detects a fault condition sends a signal to appropriate source-side, neighboring control apparatus to inhibit the source-side control apparatus from opening their respective sectionalizing switches. Further, any control apparatus that detected a fault condition and that does not receive an inhibiting signal, controls its sectionalizing switch to open. In a specific arrangement, the control apparatus that opens its sectionalizing switch also sends a signal to predetermined neighboring load-side control apparatus to open their sectionalizing switches, so as to prevent feeding into a fault condition after network restoration via a different path or source.

Title: Methods for evaluation of antimicrobial targets
Inventor: SCHMID MOLLY B
IPC: C12Q1/02
Filed: 1996-05-28
Abstract: Methods for evaluating microbial genes as targets for compounds which inhibit growth of a microbe or alter the pathogenesis of a microbe, and for evaluating the expected therapeutic effect of compounds which inhibit a reaction of a microbial cell which is related to the expression of a specific gene. The methods utilize recombinant microbes which contain DNA construct or alterations, such that the level of activity of the products of coding regions associated with those constructs of alterations can be controlled by contacting the microbe with a specific small molecule or other specific artificial environmental change. Such recombinant microbes can be used in infection models to evaluate the effect of artificially changing the level of activity of a product of a gene.

Title: Cryopreservation of diverse plant cells
Inventor: YU BIN
IPC: A01N1/02
Filed: 1996-06-07
Abstract: The present invention relates to methods for cryopreserving plant cells and to methods for recovering viable plant cells from long or short term cryopreservation. Plant cells to be cryopreserved can be grown in culture and pretreated with a solution containing a cryoprotective agent and, optionally, a stabilizer. Stabilizers are preferably membrane stabilizers such as ethylene inhibitors, oxygen radical scavengers and divalent cations. Cells can also be stabilized by subjecting the culture to a heat shock. Pretreated cells are acclimated to a reduced temperature and loaded with a cryoprotective agent such as DMSO, propylene glycol or polyethylene glycol. Loaded cells are incubated with a vitrification solution which, for example, comprises a solution with a high concentration of the cryoprotective agent. Vitrified cells retain less than about 20 % water content and can be frozen at cryopreservation temperatures for long periods of time without significantly altering the genotypic or phenotypic character of the cells. Plant cells may also be cryopreserved by lyophilizing cells prior to exposure to a vitrification solution. The combination of lyophilization and vitrification removes about 80 % to about 95 % of the plant cell's water. Cells can be successfully cryopreserved for long periods of time and viably recovered. The invention also relates to methods for the recovery of viable plant cells from cryopreservation. Cells are thawed to about room temperature and incubated in medium containing a cryoprotective agent and a stabilizer. Thecryoprotective agent is removed and the cells successfully incubated and recovered in liquid or semi-solid growth medium. The invention also relates to the cryopreserved cells and to viable plantcells which have been recovered from long or short term cryopreservation.

Patent CA-2226470-A1 (CA)
Title: Circuit for convergence setting in a projection television set
Inventor: RUNTZE ALBERT
IPC: H04N9/31
Filed: 1998-01-07
Abstract: For convergence setting, a projection television set contains photosensors (S) for the primary colours R, G, B which supply an output signal (U1) in the event of impingement of a marker (M) contained in the projected picture. The time characteristic of the output signal of the sensor while the marker sweeps over is significantly steeper and shorter for the colour blue than that for the colours green and red. This reduces the complexity of the evaluation circuit.        An integrating element lies in the path of the output signal (U1B) of the sensor (S) for the colour blue and is dimensioned in such a way that the time characteristic of the output signal of the sensor (S) for the colour blue is approximately equal to the time characteristic of the output signals (U1RG) for the colours red and green. As a result, the time characteristic becomes identical for the signals of all three sensors and the circuit is simplified.        In particular for a projection television set with convergence setting using a plurality of sensors.
